Bearing can use how long?

Bearing service performance, on the basis of the current theory development, combined with years of experience in research and development of the enterprise, the development of the corresponding bearing dynamics or quasi dynamic analysis software to support high performance bearing their r&d, Aramaki for NSK bearing dynamics analysis software package BRAIN development of rolling axis, and on cylindrical roller bearing, spherical roller bearing, four-point contact ball bearing for the real example, to carry out the bearing torque, PV value and relevant experiment to verify the exactness of the program: Stacke etc for SKF developed BEAST for rolling bearing dynamic simulation analysis software, the software can be used to keep the plane movement characteristics analysis; Sadeghi for SCHAEFFLER building with six degrees of freedom such as cylindrical roller bearing dynamics analysis model, this model can analyze transfer speed, rolling body size changes, keep the plane of symmetry on the effect on the stability of the cage. Domestic only cooperation with luoyang bearing research institute of henan university of science and technology development of rolling bearing analysis software partly integrated dynamic analysis method, the model of rolling bearing of the transient dynamic behavior analysis our country the gap existing in the field of high-end bearing, in addition to comprehensive technology level is low, the main two big bottleneck problem is raw material and manufacturing technology. In manufacturing technology, equipment and process needs a breakthrough, must take excellent equipment and advanced technology to ensure high precision and stability of high-end bearing, to ensure its high performance and stability, long life and reliability of the quality. International famous bearing company will equipment and process as one of its 'technology', from another side, illustrates the manufacturing technology is the core competitive force of enterprises. Bearing industry in China in the transformation and upgrading, it is necessary to manufacturing technology as the main parties to implement the key breakthrough in the field of high-end bearing, in order to make our country by the bearing power as soon as possible (bearing power 2) High-end application technology of the sliding bearing and industrialization of research present situation and the analysis with the rapid development of our country industry, people demand for all kinds of high performance, high parameters of equipment is more and more big. However, due to various reasons, services for high-end sliding bearing application and industrialization development is relatively backward, far cannot satisfy the needs of the host equipment development. Made in energy, power, petrochemical, and other important equipment in the field of high-end sliding bearing are in accordance with the grain imports. In the field of national defense, foreign technology blockade is providing a space for the development of their products in our country, in areas such as empty days, ships, self-developed products get a lot of application in our country, technology is relatively mature, but compared with international development frontier gap still exists
